DOOR LATCH.

Application filed May 11, 1925. Serial No. 29,536.

The object of the invention is to provide an improved construction ofthis character, especially adapted for use on garage doors, which isstrong and durable in use and may be readily operated to lock a garagedoor, or the like, in either open or closed position.

The invention consists in the combinations and arrangements of partshereinafter de scribed and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification and in which,

Fig. 1 is a front View of garage doors equipped with latches embodyingthe invention;

Fig. 2 is a horizontal section taken substantially on line 2-2 of Fig.1;

Fig. 3 is an enlarged vertical section taken on line 3-3 of Fig. 2; and

Fig. 4 is a horizontal section taken on line H of Fig. 3.

The preferred form of construction as illustrated in the drawingscomprisesan arm 5 pivotally connected at one end with a bracket 6secured to the door 7 as shown. At its other end the arm 5 is providedwith a cylindrical socket 8 into which fits a cylindrical hub 9 on oneend of an arm 10. The hub 9 is pivotally connected with socket 8 by abolt 11. At its other end the arm 10 is pivotally connected with abracket 12 secured to the under side of the upper sill 13 of the doorframe. A spring latch bolt 14 is mounted on arm 5 and arranged to engageholes or sockets 15 provided in hub 9 to lock the arms 5 and 10 invarious positions of angular adjustment.

A latch string 16 is connected with bolt 14 and passes downwardlythrough guide openings-17 in arm 5, being provided at its 1 end with aring 18. Where two doors are employed one of the latches is applied toeach door.

When the door is closed the bolt let engages one of the holes 15 andlocks the door in closed position. To open the door the latch string 16is pulled to withdraw the bolt, whereupon the door may be swung open,the arms 5 and 10 pivoting on each other as indicated in Fig. 2. Thelatch bolt 14- then engages one of the holes 15 and holds the door in.open position thus preventing accidental closing of the door by the windor otherwise. The door may be readily closed by again withdrawing thelatch bolt.

lVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect this is capable ofvariation and modification without departing from the spirit of theinvention. I therefore do not wish to be limited to the precise detailsdisclosed but desire to avail myself of such variations andmodifications as fall within the scope of the appended claims.

Having thus fully illustrated and de-v scribed my invention, what Iclaim as new and desire to secure by Letters Patent is:

1. The combination with a door frame and a door hinged in said frame ona vertical axis to swing horizontally, of an arm pivoted on a verticalaxis at one end on the frame to swing horizontally; an arm pivoted on avertical axis at one end on the door to swing horizontally; a socket onone arm and a hub on the other arm rotatabl mounted in said socket; aspring held latch bolt on said socket arm, there being latch holes insaid hub to receive said bolt; and a latch string secured to said boltfor releasing the same, substantially as described.

2. The combination with a door frame and door hinged in said frame toswing horizontally, of a first arm pivoted at one end to the frame andprovided at its other end with a cylindrical hub having a plurality ofradial holes therein; a second arm pivoted at one end to said door andhaving a cylindrical socket at its other end to receive said iub; aspring latch bolt mounted on said second arm and projecting radiallythrough said socket to engage the holes in said hub; and a latch stringsecured to said bolt for releasing the same, substantially as described.

3. The combination with a door frame and door hinged in said frame toswing horizontally, of a first arm pivoted at one end to the frame andprovided at its other end with a cylindrical hub having a plurality ofradial holes therein; a second arm pivoted at one end to said door andhaving a cylindrical socket at its other end to receive said hub; aspring latch bolt mounted on said second arm and projecting radiallythrough said socket to engage the holes in said hub; and a latch stringsecured to said bolt for releasing the same, there being a guide openingin said second arm adjacent its pivoted end and said latch stringdepending through said guide opening, substantially as de scribed.

ARTHUR HORTON.
